Laavatulvat
Laavatulvat, also known as lava flows, are streams of molten rock that erupt from a volcano and flow over the Earth's surface. The temperature of lava can range from 700 to 1200 degrees Celsius (1300 to 2200 degrees Fahrenheit). The viscosity, or thickness, of lava varies depending on its composition and temperature, influencing how far and how fast it travels. Basaltic lava, which is hotter and has a lower silica content, is typically less viscous and can flow for long distances, forming shield volcanoes and vast lava plains. Andesitic and rhyolitic lavas are cooler and more silica-rich, making them more viscous and prone to forming steeper volcanic cones.
When lava flows, it can destroy everything in its path, including buildings, infrastructure, and vegetation. However,
